4 Claims.

This invention relates to channel members such, for example, as thoseused to hold and guide the sliding window sash of an automobile, andpertains more particularly to the material for linin the channel membersso as to resiliently cushion the sash against vibration and to permit itto slide easily and quietly in the channel members.

One object of the invention is the provision of a new and improvedchannel lining of the class described which is simple in construction,inexpensive to manufacture; and effective in use.

Another object is the provision of a woven lining of this kind which isadapted for use'with materials of a relatively inexpensive nature.

To these and other ends the invention resides in certain improvementsand combinations of parts, all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawing:

Fig. 1 is a sectional view taken transversely of a window channelconstructed in accordance with one embodiment of the invention;

Fig. 2 is a transverse sectional view of a channel Fig. 5 is a viewsimilar to Fig. 4, the warp strands of the foundation weave being brokenI away for the purpose of clearness;

Fig. 6 is an enlarged fragmentary sectional view taken transversely ofthe channel lining illustrated in Fig. 3, showing the method of formingthick cushioning pads on opposite faces of the lining strip, and

Fig. 7 is a view similar to Fig. 6, the warp strands of the foundationweave being broken away as in Fig. 5, for the purpose of clearness.

The same reference numerals throughout the several views indicate thesame parts.

Referring now to the drawing, Fig. 1 shows a channel member ofsubstantially rigid sheet material such, for example, as sheet metalformed to'provide a bottom 11 and side walls 12, the free edges of whichare reversely bent to form flanges 13 spaced from the side walls 12. Alining, preferably in the form of a strip of textile fabric, is

I arranged on the inner faces of the bottom and side walls of thechannel, and is provided with spaced cushioning pads 16 and 17,hereafter dethe lining to be bent into channel form. The

pads 16 are preferably terminated short of the free edges of the stripto provide thin marginal portions 20 whichextend under and are clampedby the flanges 13.

The channel construction illustrated in Fig. 2. comprises a channelmember of sheet material similar to that shown in Fig. 1, correspondingparts being designated by the same reference numerals. The channelmember is provided with a lining, preferably in the form of a strip oftextile material, arranged adjacent the inner faces of the bottom andside walls of the channel. The strip is provided with cushioning pads16a and 17a, hereafter more fully described, woven on the outer face ofthe strip to provide cushioning means between the strip and the rigidchannel member. In this embodiment, one face of the strip is adapted toengage'the sash while the pads 16:: and 17a provide cushioning meanstherefor, and space the sash engaging portions thereof inwardly of therigid channel member. Breaks 190 are provided intermediate the pads topermit the lining to be bent into channel shape. The pads 16a areterminated short of the free edges of the lining to provide marginalportions 200 which extend under and are held by the flanges 13.

Fig. 3 shows still another modification in which the channel member issimilar to that illustrated in Figs. 1 and 2, corresponding parts beingdesignated by the same reference numerals. In-this embodiment, thechannel lining is of textile material and is provided with pads 16c andwoven on one face of the strip, and pads 16d and 17d woven on the otherface in the manner hereafter described. The pads 16c and 170 are on theouter face of the strip intermediate the strip and the walls of thechannel and space parts of the strip therefrom, and the pads 16d and 17dare on the inner face of the strip and extend inwardly therefrom toengage the sash and to provide a resilient support therefor. The padsare separated by breaks 19b which permit the lining to be bent intochannel form for insertion in the channel member. The pads 16c and 16dare terminated short of the free edges of the strip to provide marginalportions 20b which extend under and are held by the flanges 13.

In my prior application Serial No. 233,161, now Patent No. 1,847,700,issued March 1, 1932, I have described and claimed a fabric liningformed to provide pile cushioning surfaces, and in my application SerialNo. 400,125 I have described and claimed such a construction providedwith an uncut pile surface to resiliently cushion the glass sash. Thepresent invention resides in a further embodiment of the same generalcharacter; but provides a less expensive form of construction whichfacilitates the use of cheaper materials while accomplishing the desiredresult of resiliently cushioning the sash, yet permitting it to slideeasily and quietly in the channel member.

Referring now to Figs. 4 and 5, there is shown an enlarged fragmentarysectional view of the strip from which the channel lining in Fig. 1 isformed. This strip comprises a relatively thin, foundation or groundweave on the surface of which the pads 16 and 17 are woven in the mannerto be presently described. The foundation weave comprises a plurality ofwarp or longitudinal strands 25 and a plurality of weft or cross strands26 interlocked with the warp strands in the manner well known in theart.

In the present invention, each of the pads 16 and 17 comprises aplurality of substantially parallel warp strands 30 of relatively heavyinexpensive textile material, such as cotton, which are caught at spacedpoints under weft strands of the foundation weave, as clearly shown at35, Fig. 5. Intermediate these points the strands 30 extend over two ormore, in the present instance three, of the adjacent weft strands 26 toprovide long fiat resilient loops 36 which lie substantially on thesurface of the foundation weave to provide a thick padding surfaceadapted to support and cushion a sliding glass sash. The loops of theadjacent strands 30 are staggered, as shown in Figs. 4 and 5, so thateach loop cooperates with the loops of the adjacent strands to provide asubstantially flat surface in engagement with the sash. Figs. 4 and 5show only two of the heavy warp strands 30, but this is for the purposeof clearness only as it is understood that the number of such strandsmay be varied to provide pads of any desired width. The pads 16a and 17aare formed in the same manner, and are substantially the same size asthe pads 16 and 17,

above described.

It may sometimes be desirable to provide a channel lining havingresilient cushioning pads arranged on both the inner and the outer facesthereof. To this end, the present invention provides a lining, Figs. 6and '1, comprising a foundation weave similar to that shown in Figs. 4and 5 and having warp and weft strands 25c and 260 respectively. Thisfoundation weave has pads 16c and 170 woven on the outer face, and pads16d and 17d woven on the inner face thereof, as shown in Fig. 6. Each ofthe pads 16d and 17d is formed of heavy warp strands 30d, of the samematerial as the strands 30. which are caught at spaced points under weftstrands 26c of the foundation weave, as shown at 350 Fig. '7.Intermediate these points, the strands 30d extend over two or more, inthe present instance three, of the adjacent weft strands 260 to providelong fiat loops 3611 which lie on the inner face of the strip to provideresilient cushioning pads in engagement with the sash. The strands 30dare preferably smaller than the strands 30 for obvious reasons.

While the pads 16d and 17d are arranged to engage the sash, the pads 16cand 17c are disposed intermediate the lining and the walls of the rigidchannel to space the sash engaging portions of the lining therefrom.Each of the pads 16c and 170 comprises a plurality of warp strands 300of textile material preferably, although not necessarily, of smallerdiameter than the strands 30d. These smaller strands are caught atspaced intervals under the weft strands 260 of the foundation fabric, asshown in Fig. '7. Intermediate these points, the strands 30c extend overtwo or more, in the present instance, three, adjacent weft strands toprovide long flat loops 36c arranged on the outer face of the lining toprovide cushioning pads or between the lining and the walls of the rigidchannel member.

It is apparent from the above description, that the present inventionprovides a channel lining of an inexpensive construction whichfacilitates the use of materials of a less expensive nature, and whichresiliently supports the sash against vibration and permits it to slideeasily and quietly in the channel member.

While one embodiment of the invention has been disclosed, it is to beunderstood that the inventive idea may be carried out in a number ofways. This application is therefore not to be limited to the precisedetails described, but is intended to cover all variations andmodifications thereof falling within the spirit of the invention or thescope of the appended claims.
